There is disclosed a process for performing an isolated Pd(II) mediated oxidation reaction electrochemically. The inventive process is performed on an electrode array device having a plurality of separately addressable electrodes. Preferably, the Pd(II) mediated oxidation is a Wacker reaction. Specifically, there is disclosed a process for conducting an isolated Pd(II) mediated oxidation on a plurality of electrodes, comprising providing an electrode array device having a plurality of electrodes with a conductive electrode surface and a matrix or coating material over the electrodes surfaces; providing a solution bathing the electrode array matrix or coating material and electrode surfaces, wherein the solution comprises a transition metal species and a confining agent; and biasing one or a plurality of electrodes (“selected electrode or electrodes”) with a voltage or current to regenerate the transition metal species required for the isolated Pd(II) mediated oxidation, whereby the confining agent limits diffusion of the transition metal species to a volume surrounding each selected electrode surface.
所披露的是一种用电化学方法进行隔离的Pd(II)催化的氧化反应的过程。该发明过程是在具有多个独立寻址电极的电极阵列设备上进行的。优选地,Pd(II)催化的氧化是一种Wacker反应。具体来说,所披露的是一种在多个电极上进行的隔离Pd(II)催化的氧化过程,包括提供一个具有多个电极的电极阵列设备,电极具有导电电极表面和覆盖在电极表面的基质或涂层材料;提供一个溶液来浸泡电极阵列基质或涂层材料和电极表面,其中该溶液包含过渡金属物种和限制剂;以及偏置一个或多个电极(“选定电极或电极”)以电压或电流再生进行隔离Pd(II)催化的氧化所需的过渡金属物种,从而限制剂限制了过渡金属物种向包围每个选定电极表面的体积内的扩散。
